Step-by-Step
- Sign on plain white paper with a black or dark blue pen.
- Scan the paper (or photograph clearly in good light) and upload the image to ImgPace.
- Open Crop, click the 400:150 Signature ratio, drag the crop box to cover only the signature, Apply Crop.
- Open Resize, enter the exam-specific pixel dimensions (e.g., 140×60 for IBPS/SBI, 600×150 for SSC), uncheck "Lock aspect ratio", Apply Resize.
- Open Compress, select the ≤ 20 KB chip, click Apply Compression.
- Download the signature JPEG and upload to the exam portal.
Tips for a Clean Signature Scan
- Use a fine-tip dark pen — thin strokes look crisp after compression.
- Scan at 300 DPI for best clarity; anything less looks pixelated.
- Avoid coloured paper — it adds JPEG weight unnecessarily.
- If the background is off-white, use Enhance (increase contrast, brightness) before cropping.
Frequently Asked Questions
How do I get my signature below 10 KB without losing quality?
Signatures are almost all white pixels, so JPEG compresses them extremely efficiently. Pick Manual Quality in Compress and drop to 40–60% — you can usually reach 5–8 KB with no visible degradation.
The portal rejects my signature for being "too light".
Use the Enhance tool — increase contrast to +40 and brightness to −20. This darkens pen strokes against white. Then compress.
Can I sign on a touchscreen and use that?
Yes — export the signature as a PNG with transparent background, upload to ImgPace, use Background Fill → White to replace the transparent pixels, then apply the normal crop + resize + compress flow.
